Stomatognathic disease refers to the diseases of the mouth ("stoma") and teeth ("gnath"). The etymology is similar to that of the term Gnathostomata. It is the term used by MeSH (along with the synonym dental diseases), but other organizations use different terms.

The American Dental Association uses the term "oral and maxillofacial pathology", and describes it as "the specialty of dentistry and pathology which deals with the nature, identification, and management of diseases affecting the oral and maxillofacial regions. It is a science that investigates the causes, processes and effects of these diseases."[1]
